We’ve also got a roundup of the best 10” table saw blades.

Size

Both saw blades are 10” in diameter and have a 5/8” arbor hole. Most table saws have a 5/8” arbor and can accommodate blades up to 10” in diameter. So both table saw blades should be widely compatible with many saws.

Both products have a 1/8” (full) kerf. The 10” x 40T Woodworker II is 0.09” thick. (The term “kerf” refers to the width of the cut that the blade makes in the material being cut.)

A 1/8” kerf is considered a “full” kerf and should work with most table saws. On lower-powered saws, a full-kerf blade might cause the saw to struggle with thicker or harder material, compared with a thin-kerf blade.

Teeth

Both blades have C4 carbide teeth in an ATB configuration. The 10” x 40T Woodworker II has 40 teeth. The 10” x 24T ATB has 24 teeth.

Blades with fewer than 40 teeth are typically geared towards ripping wood lengthwise. For crosscuts or general-purpose use, you might consider blades with a higher tooth count. Blades with between 40 and 60 teeth are usually considered general-purpose blades. They will be adequate for both ripping and crosscutting, but not quite like a blade specifically made for those cuts.

Alternate top bevel (ATB) teeth are cut on a bevel rather than being flat across. This shape lets them slice through wood rather than tearing out chunks, leading to cleaner crosscuts. They do tend to be less durable than flat-top teeth.
